Using the Injen intercooler is easy. Just install it as a direct - fit unit according to the provided instructions. No need to modify your Mustang. When using it, make sure the connections with the piping are secure. For maintenance, regularly check for any signs of damage, like cracks or leaks in the cast end tanks or flanges. Keep the intercooler clean from dirt and debris. If you use Injen's aftermarket charge pipes, also check their condition. This will help ensure the intercooler keeps reducing intake temperatures and boosting your Mustang's performance.
